Abstract

There are provided a power measuring apparatus capable of accurately obtaining metering information and being manufactured at low cost by storing the metering information in an internal flash memory and an operating method thereof. The power measuring apparatus includes: a controlling unit controlling processing of consumed power metering information; a flash memory storing the metering information according to the controlling of the controlling unit and storing an operating program with respect to the processing of the metering information; and a random access memory providing a substitution program substituting the operating program while the metering information is stored in a specific address of the flash memory.

Claims

1. A power measuring apparatus, comprising:

a controlling unit controlling processing of consumed power metering information;

a flash memory storing the metering information according to the controlling of the controlling unit and storing an operating program with respect to the processing of the metering information; and

a random access memory providing a substitution program substituting the operating program while the metering information is stored in a specific address of the flash memory.

2. The power measuring apparatus of claim 1, wherein the flash memory includes:

a metering calculation region in which measured metering information is calculated;

an operating program region in which the operating program is stored;

an interrupt service routine region providing a corresponding service routine when a preset internal interrupt is generated; and

a data region providing a data storage address.

3. The power measuring apparatus of claim 2, wherein the random access memory provides a corresponding service routine when a non-preset external interrupt is generated.

4. The power measuring apparatus of claim 1, further comprising a measuring unit having a metering algorithm measuring the metering information.

5. A method of operating a power measuring apparatus, comprising:

calculating measured metering information;

providing a corresponding service routine stored in a flash memory when a preset internal interrupt is generated; and

providing a corresponding service routine stored in a random access memory when a non-preset external interrupt is generated.

6. The method of claim 5, wherein the flash memory includes:

a metering calculation region in which the measured metering information is calculated;

an operating program region in which an operating program is stored;

an interrupt service routine region providing a corresponding service routine when the preset internal interrupt is generated; and

a data region providing a data storage address.

7. The method of claim 6, wherein the random access memory provides a substitution program substituting the operating program while the metering information is stored in a specific address of the flash memory.
